GAS-METER.

Application filed January 4, 1917.

To all whom it may concern:

Be it known that I, RICHARD LEE DEZEN- DORF, a citizen of the UnitedStates, residing at 432 Guion ave, Richmond Hill, county of Queens, andState of New York, have invented certain new and useful Improvements inGas-Meters, of which the following is a full, clear, and exactdescription.

My invention relates to improvements in gas meters and has for itsobject to provide a novel, simple and eilicient means for adjustablymounting the tangent post upon the tangent, so that its angular relationto the crank shaft may be varied as well as radial position, in order toadjust its position for correct operation.

The following is a description of an embodiment of my invention,reference being had to the accompanying drawings, in which:

Figure 1 shows a plan view of a meter embodying my invention, the metertop being removed;

Fig. 2 shows a side elevation of the meter tangent and the adjustablepost thereon;

Fig. 3 shows in perspective the tangent together with the means foradjusting the tangent post, and

Fig. 4 shows a detail end View of the tangent and the movable membercarry ng the tangent post, together with the adjusting screws co-actingtherewith, one of the adjusting nuts being removed.

Referring more particularly to the drawings, 1 is a meter case with thetop removed, having the inlet 2 and the outlet 3; 4 is a registeringtrain actuated by the shaft 5, driven by the gear 6, which in turn isdriven by the worm 7 carried by the upper end of the ordinary crankshaft; 8 is the tangent carrying the tangent post 9, to which areconnected the lower flag arms 10 and 11, which in turn are connected tothe upper flag arms 12 and 13, carried by the flag wires 14 and 15respectively.

In order to adjust a tangent post relatively to the crank shaft, it isnecessary at times to move the tangent post through a small angle aboutthe crank shaft. This has generally been done by unsoldering the tangentand re-soldering it in a. new position. It also has been done bymounting the tangent post upon a movable member having an axis ofrotation concentric with the axis of the crank shaft. I have found thatgood re- Specification of Letters Patent.

sults can be produced in a simpler manner and in carrying out my presentinvention provide a. yoke 16 upon which the tangent post 9 is rigidlymounted. This yoke has an elongated opening surrounding the body of thetangent so as to be laterally movable thereon. In the ends of this yokeare adjusting screws 17, whose inner ends engage the body of thetangent, as shown in Fig. 4. On the two sides of the adjustable yoke arenuts 18 and 19 engaging screw threads upon the body of the tangent andserving as means for adjusting the yoke 16 upon the tangent at thedesired radial distance from the axis of the crank shaft. The upper andlower sides of the tangent are provided with horizontal surfaces whichengage plain surfaces of the opening in the yoke so as to guide the yokeand maintain the tangent post in a vertical position.

In using my improved adjustable tangent post, I first loosen the screws17 and by means of the nuts 18 and 19 move the yoke and tangent postlengthwise upon the tangent so that the distance between the axis of thecrank shaft and the axis of the tangent post is substantially thecorrect radial distance; I then move the yoke 16 to one side or theother by means of the adjusting screw 17 in which the proper angularrelation between the tangent post and the crank shaft is obtained, and Ithen clamp the yoke permanently in that position by means of the screws17 and nuts 18 and 19. By this means the angular position of the tangentpost can be adjusted without moving the tangent relatively to the crankshaft to which it is soldered. The adjustable yoke and post can beapplied to old meters having the ordinary tangent, soldered to the crankshaft in the ordinary manner.

As will be evident to those skilled in the art, my invention permits ofvarious modifications, without departing from the spirit thereof or thescope of the appended claims.

l/Vhat I claim is:

1. In a gas meter, the combination of a straight tangent, a yokecarrying a tangent post rigidly mounted thereon and having ahorizontally elongated opening therein, said opening surrounding saidtangent and having its major axis horizontal and substantially at rightangles to said tangent, and clamping nuts surrounding said tangent andengaging the sides of said yoke, the axis of said nuts being in linewith the axis of said tangent.

2. In a gas meter, the combination of a straight tangent, a yoke havinga horizontally elongated opening therein having its major axissubstantially at right angles to said tangent, and clamping nuts on saidtangent engaging the sides of said yoke, and adjusting screws enteringthe ends of said yoke for moving the same laterally relatively to saidtangent.

Copies of 3. In a gas meter, the combination of a straight tangent, ayoke having a horizontally elongated opening therein having its majoraxis substantially at right angles to said tangent, and clamping nuts onsaid tangent engaging the sides of said yoke, said tangent having ahorizontally extending guiding surface engaging the inner horizontalsurface of said opening.
